4.Replace the cold-aisle temperature sensor cover (1).

5.Replace the four screws that secure the cold aisle temperature sensor cover (2).

Temperature sensors (hot aisle)

The HP POD 20c contains three temperature sensors in the hot-aisle.

You need a screwdriver to remove and replace the hot aisle temperature sensors.

Removing the hot aisle temperature sensor

1.Remove the four screws (1) that secure the hot-aisle temperature sensor cover, and then remove the cover (2).

2.Label the hot-aisle temperature sensor wires or take a picture to remember which wires to reconnect later.

3.Disconnect the wires.
